Den unge lejonhanne som röt men aldrig flög : Om ett israeliskt stridsflygplan och de lärdomar det kan förmedla till Gripen

Polyhydroxyalkanoate synthase (PhaC) : The key enzyme for biopolyester synthesis

Polyhydroxyalkanoates (PHAs) are considered good candidates in replacing commercial petrochemical plastics in certain applications like single-use packaging since they are biodegradable, biocompatible and share similar properties with conventional plastics. PHA synthase (PhaC) is the key enzyme in PHA biosynthesis. There are four classes of PhaC, namely, class I, class II, class III and class IV,

Long-Read Sequencing Reveals Genetic Adaptation of Bartonella Adhesin A Among Different Bartonella henselae Isolates

Bartonella henselae is the causative agent of cat scratch disease and other clinical entities such as endocarditis and bacillary angiomatosis. The life cycle of this pathogen, with alternating host conditions, drives evolutionary and host-specific adaptations. Human, feline, and laboratory adapted B. henselae isolates often display genomic and phenotypic differences that are related to the express

Train Passes and Dwell Time Delays

Traffic on railways is increasing and this makes train traffic to be highly interconnected . This paper investigates how passing of train affects dwell time delays in Sweden. Three scenarios are considered by combining the scheduled and actual operations: passes that happened as scheduled, unscheduled passes that happened in operations, and scheduled passes that were cancelled. A logistic regressi

Passenger flows and dwell times for commuter trains in Stockholm

This study investigates how the volume and flow of passengers affect dwell times, usingdata from commuter trains in Stockholm. We show that dwell times often take longer thanscheduled and that most station stops involve rather limited numbers of passengers.Improving the performance at these stops with small volumes can thus have a sizeableimpact on the overall on-time performance.

New Insights into the Interaction of Class II Dihydroorotate Dehydrogenases with Ubiquinone in Lipid Bilayers as a Function of Lipid Composition

The fourth enzymatic reaction in the de novo pyrimidine biosynthesis, the oxidation of dihydroorotate to orotate, is catalyzed by dihydroorotate dehydrogenase (DHODH). Enzymes belonging to the DHODH Class II are membrane-bound proteins that use ubiquinones as their electron acceptors. We have designed this study to understand the interaction of an N-terminally truncated human DHODH (HsΔ29DHODH) an

Computer simulation of spontaneous speech

This paper pinpoints some of the problems faced when a computer text production model (COMMENTATOR) is to produce spontaneous speech, in particular the problem of chunking the utterances in order to get natural prosodic units. The paper proposes a buffer model which allows the accumulation and delay of phonetic material until a chunk of the desired size has been built up. Several phonetic studies

The Forward Physics Facility: Sites, Experiments, and Physics Potential

The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider during the High Luminosity era. Located along the beam collision axis and shielded from the interaction point by at least 100 m of concrete and rock, the FPF will house experiments that will detect particles outside the acc

Brokerage activity, exclusivity and role diversity: A three-dimensional approach to brokerage in networks

The purpose of this paper is to connect central theoretical contributions to the study of brokerage and propose a novel conceptual and analytical approach for investigating it. On one hand, it builds on, and further substantiate the utility of, the innovation of conceptualizing brokerage activity and brokerage exclusivity separately, whilst analyzing them together. On the other hand, it also build

National cohort of infants born before 24 gestational weeks showed increased survival rates but no improvement in neonatal morbidity

Aim: To describe survival and neonatal morbidities in infants born before 24 weeks of gestation during a 12-year period. Methods: Data were retrieved from national registries and validated in medical files of infants born before 24 weeks of gestation 2007–2018 in Sweden. Temporal changes were evaluated. Results: In 2007–2018, 282 live births were recorded at 22 weeks and 460 at 23 weeks of gestati
